[0018] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0019] For example Figures 1 to 6As shown, the utility model is a kind of easily assembled and disassembled down lamp, it is mainly by down lamp body (1), anti-dazzle cover (2) and pre-embedded part (3) composition.Compared with traditional down lamp, the utility model is separated from pre-embedded part (3) on down lamp to obtain the optimization of structure by independent installation, specifically, the inner side of pre-embedded part (3) is designed with positioning spring (31), to be able to flexibly, quickly and stably movable assembly to the down lamp body (1) with anti-dazzle cover (2) after pre-embedded part (3) is set in ceiling, specific structure is as follows:

[0020] Screw hole (30) is formed on the pre-embedded part (3), and it is fixed on the ceiling with mounting hole by screw hole (30) and screw;The down lamp body (1) is movably connected with the anti-dazzle cover (2) by M3 screw (19) with spring;The inner wall of the pre-embedded part (3) is provided with a "V"-shaped positioning spring (31);The outer wall of the anti-dazzle cover (2) is designed and formed with a positioning groove (20) embedded with the positioning spring (31) for clamping installation;The down lamp body (1) connected with the anti-dazzle cover (2) is movably assembled into the pre-embedded part (3) by the cooperation of the positioning groove (20) and the positioning spring (31).

[0021] Among them, M3 screw (19) with spring is used as connecting piece, the down lamp body (1) can be adjusted in displacement within the compression or reset range of spring after being movably connected with the anti-dazzle cover (2), as Figure 7 As shown, such structure design can make the middle ring move up and down, the purpose is to move the down lamp body (1) up to have a force point when disassembling to facilitate disassembly, or to move down to lock to restore the down lamp body (1) to the assembly position close to the anti-dazzle cover (2).

[0022] It should be noted that the positioning spring (31) should be two or more, and equidistantly arranged, so that the stability of assembly clamping can be improved to the greatest extent after assembly.As for the positioning spring (31), the pre-embedded part (3) is provided with a window (32) at the position of the positioning spring (31), which can be used when the user needs to disassemble the down lamp body (1), the user moves the positioning spring (31) outward at the window (3) of the pre-embedded part (3) to make it separate from the positioning groove (20), and then the down lamp body (1) can be disassembled by being pushed out or pulled out upward.

[0023] It can be extended that the down lamp body (1) is composed of a terminal (10), a rear cover (11), a PCB board (12), a radiator (13), a COB light source (14), a light source plastic part (15), a lens (16), an inner ring (17) and a middle ring (18), wherein the PCB board (12) is provided with an insulating box (120) to assemble and arrange, so that the structure design can ensure that the down lamp body (1) has excellent service life and working effect.

[0024] It is worth mentioning that the down lamp body (1) is connected with the anti-dazzle cover (2) through the middle ring (18), specifically, the middle ring (18) is formed with an inner toothed threaded guide column (180) penetratingly designed, and the anti-dazzle cover (2) is formed with an inner toothed threaded connecting guide column (21) opposite to the inner toothed threaded guide column (180), the inner toothed threaded guide column (180) and the inner toothed threaded connecting guide column (21) need to be on the same axis during assembly, so that effective and stable fixed connection can be achieved.

[0025] Regarding the positioning elastic sheet (31), it is designed in a sheet structure and has the characteristics of elastic deformation, can expand outward to make room for assembly when the anti-dazzle cover (2) falls down and press in, and can reset to enter the positioning groove (20) to clamp and fix the anti-dazzle cover (2) connected with the down lamp body (1) after the anti-dazzle cover (2) reaches the designed position, thus the down lamp body (1) can be stably assembled in the embedded part (3) on the ceiling. And thanks to the "V" shaped design of the positioning elastic sheet (31), the slope design on both sides thereof can make the down lamp body (1) expand outward to make room for assembly after approaching and contacting, so that the positioning elastic sheet (31) can fall into the positioning groove (20) to clamp and fix the assembly whether the down lamp body (1) is placed into the embedded part (3) from bottom to top or from top to bottom, such design greatly facilitates the user's assembly, and when disassembling, the positioning elastic sheet (31) can be bent outward at the window (32) of the embedded part (3) to lift out the down lamp body (1) or catch the down lamp body (1) falling downward based on gravity, so that the down lamp body can not only achieve quick assembly and disassembly effect when daily maintaining and replacing the down lamp, but also realize the same stable and practical purpose during installation and use.
